Principals of the 70 schools have asked the Suid-Afrikaanse Onderwysersunie director of operations not to release the names of the institutions, fearing that it could cause panic.

A tragedy similar to the one at Hoërskool Driehoek is possible at 70 schools in South Africa, after they were red-flagged for structural defects.

On February 1, the country mourned the death of four pupils after a concrete slab above a corridor at Hoërskool Driehoek in Vanderbijlpark collapsed. Twenty-two pupils were injured and some of the injuries were severe injuries.

On Friday, the Suid-Afrikaanse Onderwysersunie (SAOU) released its national survey on school infrastructure where it identified 70 schools nationally as on the brink of collapse.
